Looks like you had a great Christmas!  Looking forward to the progress!

Good to see that project started Butch! I concur in most respects that Indian design departures from the Dursley originals usually carry some issues... The only ones that appear to be truly viable improvements are 750 rpm (big bore and stroke) 18/1 singles. These I have not found significant faults with, and expect to re-stock here shortly. Other than those, I am pleased with the original designs in simplicity and performance... no need to re-invent.

I am likewise glad to see your content has survived shipping and storage and more shipping and more storage without blemish. We do not always get quite that lucky although the parts and the crates are quite rugged. Some crates have arrived upside down and broken, some have been rain soaked during storage/transit. These days we really have to dismantle all overseas packaging and start over to insure the quality of what goes out our doors.

Thanks for your valuable documentation and lots of pictures and commentary!

Teardown time is also observation time.  We have gibb key issues. Twin or single if you have keys that look like this you are inviting flywheel problems that are expensive to fix. Since it was not covered in the build thread it will on this build.

Other than being way too long, or else not being driven all the way in, and they fall out, what is wrong ?

If it's loose, I can see it backing out and chewing up the hub, but if it's tight, and there is some engagement inside the hub, what's the issue ?

The tapers on those keys are often needing adjustment to fit properly to the crank and flywheel. Sometimes they lack the taper altogether. With a proper taper, they will go all the way into the slot to within about 3/8 to 1/2 inch of the flywheel and be fully tightened. I know it is much better to see them this way (easily removed and adjusted), than driven in too far with a 20lb sledge!  I have seen that problem and it can present a real challenge to remove without damage.

A good dressing with a sharp file will fix the issue in most cases. I also like to use a little bench belt sander around the shop for minor adjustments as well.

Butch, you most likely have some good rule-of-thumb wisdom on the topic... bottom line, don't trust the Indian finished parts to be perfect right out of the box.

Looks like what I removed from my twin
by the same method.

I ended up with about 1/2 cup by the time I got
done.

As before I saved some bandwidth by not documentin the tear down. We are now at the point of beginning. Beside the normal cleaning we have some modifications to preform. As shipped there is no way to check the oil level or add oil except by removing  the crankcase cover. We will be addressing that during  block prep.

looking at the block pic my metro 12/2 center crank bearing supported by bolts from the top, yours from the block casting from the base? any comments?
